+	//! Base class of most objects of the irrKlang.
+	/** This class provides reference counting through the methods grab() and drop().
+	It also is able to store a debug string for every instance of an object.
+	Most objects of irrKlang are derived from IRefCounted, and so they are reference counted.
+
+	When you receive an object in irrKlang (for example an ISound using play2D() or
+	play3D()), and you no longer need the object, you have 
+	to call drop(). This will destroy the object, if grab() was not called
+	in another part of you program, because this part still needs the object.
+	Note, that you only don't need to call drop() for all objects you receive, it
+	will be explicitely noted in the documentation.
+
+	A simple example:
+
+	If you want to play a sound, you may want to call the method
+	ISoundEngine::play2D. You call
+	ISound* mysound = engine->play2D("foobar.mp3", false, false true);
+	If you no longer need the sound interface, call mysound->drop(). The 
+	sound may still play on after this because the engine still has a reference
+	to that sound, but you can be sure that it's memory will be released as soon
+	the sound is no longer used.
+
+	If you want to add a sound source, you may want to call a method
+	ISoundEngine::addSoundSourceFromFile. You do this like
+	ISoundSource* mysource = engine->addSoundSourceFromFile("example.jpg");
+	You will not have to drop the pointer to the source, because
+	sound sources are managed by the engine (it will live as long as the sound engine) and
+	the documentation says so.
